CROSSLOCK_
DormantCROSSLOCK is a ransomware operator tracked through its public data-leak infrastructure. The group operates under the double-extortion model that defines the modern ransomware ecosystem — file encryption combined with the threat of stolen-data publication on a public leak site — and continues to post fresh victim claims as part of an ongoing extortion campaign.

Claimed vs confirmed. The figures above the fold on this page come from Crosslock's own leak-site postings and reflect what the operation claims. The table here is a separate evidence class: incidents Ransomnews verified against a public source. Confirmed counts are lower than claimed counts by design — most victims never disclose, and some leak-site listings are recycled, exaggerated or fabricated. Records and ransom figures are shown only where a named source disclosed them. See the full ransomware statistics or the Ransomtracker dataset.
